Workshop Network Connection
The DISplus has the ability to be integrated into an existing workshop computer network.
Networking allows the DISplus to be connected to the same server as the DCS 2000
system.
Having all of the BMW centers diagnosis equipment on a network, provides BMW with a
method of immediate retrieval of data from vehicle systems that are being diagnosed in the
workshop.
The benefits are, to provide BMW with a better, more complete and in-depth understanding of diagnostic problems and the conditions of diagnosable systems. Also, this information will be used by the Hotline and by Service Engineering to support BMW centers, as
well as for product improvement and development.
In addition to reporting, the DISplus will add a web browser feature. This will enable
technicians to toggle over to the internet and view information on the technical
website.
The Workshop Network consists of:
• DISplus
• Ethernet drop from the BMW center’s DCS 2000 LAN
• Switched hub
• Ethernet Access point with RF transceiver
• Diagnostic bay(s) wired with 3 Ethernet 10base-T connections
• Technical Reference PC (located in the workshop)
• Network Printer: Lexmark M410N post script printer
• I/P address for each device on the Ethernet

Network Terms Defined
Ethernet
Originally developed by XeroxTM, Ethernet is the most widely used LAN technology. An
Ethernet LAN typically uses coaxial cable or twisted pair wiring. The most common
Ethernet systems are called 10base -T and provide transmission speeds up to 10Mbps.
Internet Protocol (I/P) Address
An Internet Protocol address is a binary number that identifies each sender or receiver of
information that is sent across the internet or LAN. The I/P address is usually expressed
as four decimal numbers, each representing eight bits, separated by periods i.e.
192.168.68.20. The numbers and their sequence provide information to the Network
about which specific device or Host is sending or receiving a message.
Local Area Network (LAN)
A local area network is a group of computers and devices that share a common communications line and may share the resources of a single server within a small geographic area
i.e. within a Dealership. Shared programs can be kept on the LAN server and be accessed
by individuals on the LAN. Also, for example, users can order printing from one centrally
located printer attached to the LAN.
10base-T
Most Ethernet wiring uses ordinary twisted pair phone line to transfer data within a LAN.
The designation, 10base-T is an Institute of Electrical and Electronics Engineers shorthand.
“10” refers to the transmission speed of 10Mbps (megabits per second). Base means that
only Ethernet signals are carried on the line. “T” represents twisted pair. There are other
media used to transfer Ethernet signals that can use coaxial cable or fiber optical cable.

Diagnosis and Information Systems
Establishing a Connection With the Diagnostic Head
•
Attach the diagnostic cable to the
head. The cable will only fit in the correct
socket.
Note:
Use the correct cable according to the type of
diagnosis socket that the vehicle has (16 pin OBD
II or BMW 20 pin under the hood).
•
Connect the diagnostic cable to the
vehicle.
•
Turn on the ignition.
•
As a test, all three LEDs will illuminate.
The green LED should stay illuminated to
indicate that the head is receiving
operating power.
•
The amber LED will flash until a
connection to the DISplus can be
established.
•
As soon as the LAN connection with the DISplus is established, the flashing amber LED
will change to a steady light.
•
Connection to the Diagnostic Head of the DISplus can be confirmed and created from
the “Connection Setup” screen of the Administration page.
15
Diagnosis and Information Systems
•
If Radio-LAN communication with the
Diagnostic Head is not possible, a hardwire
cable connection may be made.
DK LAN Cable
•
Connect the DK LAN cable as shown in the
illustration (orange connector).
•
On the DISplus, disconnect the SE LAN
cable (the one connecting the DISplus to the
network). Connect the other end of the DK
LAN cable (that looks like a phone
connector) to the DISplus LAN receptacle.
•
Restart the Head by briefly disconnecting and connecting it to the vehicle to initialize
communication.

The counter function of the DISplus measurement system allows the user to measure time
based signals. The measurements are:
• Frequency
• Period
• Pulse duration
• Pulse duty factor
25
Diagnosis and Information Systems
The desired measurement is set-up from the screen by selecting from the following:
• Measurement function
• Test cable
• Measurement range
• Trigger level (default is set at 5 Volts)
• Trigger slope (determines which portion of the signal will be used as the trigger point)
Oscilloscope Function
The oscilloscope function of the DISplus uses a digital dual trace display screen. There are
two methods for setting up the scope to display a pattern: manual setup or preset
measurements.
The oscilloscope setting screen is used to manually select how the measured signal will be
displayed.

Once the settings are complete and the test connections are made the oscilloscope graph
may be viewed by selecting the “Oscilloscope display” button.
The oscilloscope signal pattern may be adjusted by manipulating the voltage level and the
trigger level (voltage) from within the display screen. If the displayed pattern is still unreadable or incorrectly setup, the oscilloscope settings can be further adjusted by returning to
the settings screen.

Oscilloscope display screen features
Once the signal pattern is displayed, the pattern may be locked on the screen with the
“Hold screen” button or with the freeze image buttons on the test cable leads.
Holding the image will activate the “Cursor”, “Zoom” and “Memory” features. Holding the
image also allows the signal pattern to be visible when printing the screen.
Cursor 1 and 2
This feature is used to measure the amplitude and time differential of the signal pattern.
Activate the feature by pressing the Cursor 1 button first. A vertical line will appear.
Roughly position the line by touching the desired measurement point on the screen.
Anywhere the cursor line intersects the signal pattern, the amplitude value at that point will
be displayed in a box on the right of the display screen. If both traces of the scope are
being used, (both channel A and B) each value will be shown in its own box. A fine adjustment may be made to the cursor line by using the arrow buttons to the left and right of the
cursor buttons.
The time differential between two points may be measured if cursor 2 is used. Place the
second cursor at the desired measurement point. The time difference between the two
cursors will be displayed in the “Time value” box on the right side of the screen.

Zoom
By selecting the “Zoom” button, a section of the signal pattern may be enlarged to show
greater detail. The desired section of the display is called up by touching the screen at the
desired spot.
Memory
Memory pages are stored every time the Hold Screen is activated. The DISplus stores the
last 10 trigger pulses at the time the screen is held. To recall the memory pages, press the
“Memory” button and use the left arrow button to scroll through the previous 9 pages (page
10 is already displayed). The cursor and zoom features may be used on the stored pages.
Preset Measurements
The preset measurements provide an easy method of testing several commonly measured
signals. To enter the presets: Press the “Preset measurements” button on the bottom of
the screen. A pop up window will provide several signals to choose from. Selecting the
signal and pressing the OK button will automatically configure the oscilloscope to the settings needed to provide the best trace pattern. Many tests also have specialized boxes
with additional readings( i.e RPM, system voltage).
For instructions on which cables to use for the preset test, follow the instructions in the
“Preset measurements” selection of the “Help” menu.
Since the oscilloscope settings are pre-determined, no changes to the oscilloscope are
possible.
